Valeo makes your car engine hybrid

August 02, 2012 // By Anne-Françoise Pele
Hybrid cars are still too expensive, and not everyone can afford to buy one. But automotive supplier Valeo said it has recently launched an affordable hybrid concept for the mainstream.

Interviewed by French radio station Europe 1 , Henri Trintignac, Valeo's director of Electric Vehicle Activity, claimed that Valeo SA has developed an electrification solution for the powertrain, Hybrid4All, which enables car manufacturers to turn a traditional engine – diesel or gasoline - into a hybrid engine, at an affordable price by using simple and standardized components.

Valeo claimed the “Hybrid4all” architecture is based on a compact motor generator which uses a low voltage electrical system (48V). Costs are thus reduced, making this solution more acceptable for the mass market.

In the “Hybrid4all” architecture, the electric motor, which assists the ICE, can be installed in different positions: in front of the ICE (on the accessory drive belt), after the gear-box or between the two. This solution integrates Valeo's enhanced Stop-Start, regenerative braking and torque assist functions.

The system is claimed to enable fuel savings of more than 15 percent on an average gasoline engine vehicle. The original “Hybrid4all” electro-technical architecture means that the motor generator provides a high level of power (up to 15kW) and takes up no more room than a conventional alternator.

Valeo said "Hybrid4all" recovers energy during deceleration (regenerative braking), and re-uses it during acceleration assisting the combustion engine.

 "This system enables to reduce CO2 emissions by 15 percent," told Trintignac to Europe 1 . A car driver now spending 100 euros ($120) per month will see his/her fuel budget drop to 85 euros ($102), he continued.

Valeo claimed a 15.5-percent CO2 reduction with a prototype car, a Peugeot 207 1.6 L THP. The system is designed for small cars such as the Renault Twingo, Clio and Opel Corsa. So far, these car models could not be equipped with hybrid engines because of the cost.

Cars equipped with the electrical system are expected to be available in 2017, Trintignac concluded.
